I just cut the shirt underneath the armpits, roll-hemmed the waist & put the elastic in it. I didn't even have to touch the hem. It was already done for me. Sew easy! Now I'm looking all through my closet to see what other shirts would make cute skirts for my girls.
I also made a few other skirts with just plain old fabric. Nothing too tricky about these. Just a pattern & fabric.
and, yes, that is a pool table in our living room. But, that's a whole other story.
author's note: Please don't look too closely at those skirts. My sewing skills are lacking. Did I mention I absolutely hate sewing?
